If 10 grains of sand fall in an hourglass every second, then the total number of grains that fall in an hour = 10/sec x 60 sec/min x 60 min/hour = 36,000 grains per hour.
Interestingly, this is very close to the number of days in our lives if we live to be 100, i.e. 365.25 x 100 = 36,525.
Thus, the phrase "Like the sands through the hourglass, so are the Days of Our Lives" spoken in every episode of the TV series "Days of Our Lives" is closer to the truth than I think the original writers realized.
sand is crushed up rocks into fine grains but the specific thing that makes glass is the Silicon Dioxide
Sand is not a compound and haven't a molar mass; also different types of sand exist.
It is challenging to determine the exact number of grains of dirt in a sand dune, as it can vary greatly depending on the size of the dune. However, a rough estimate is that there are billions to trillions of grains of sand in a typical sand dune.
Silica sand is typically white or light-colored and has a grainy texture. It is made up of small granules that are smooth and shiny when viewed up close. The sand is a key ingredient in making glass as it provides the silicon dioxide needed to melt and form into glass.
There are many more stars than there are grains of sand on earth. See link.
The number of grains of sand in an hourglass can vary depending on its size and design. However, a typical hourglass may contain around 10,000 to 15,000 grains of sand.
The number of grains of sand in a 30-minute hourglass can vary widely depending on the size of the grains and the design of the hourglass. However, a typical hourglass might contain anywhere from several hundred to several thousand grains of sand. For example, a standard hourglass might hold around 1,000 to 2,000 grains of sand to measure the 30-minute duration. Ultimately, the exact number would depend on specific measurements of the hourglass used.

An hour glass works by there being sand in one side of a jar and in the middle of the jar the glass is really thin. So once the sand gets to the other side it measures to 30 minutes.
Another name for sand clock is hour glass

It is estimated that there are approximately 41 million grains of sand in a gallon. This number can vary depending on the size and shape of the sand grains.
too many to count!
